CHAIR ATTACHMENT.

Specification of Letters Patent.

Patented Sept. 12, 1911.

Application filed January 16, 1911. Serial No. 602,804.

To all whom it may concern:

Be it known that I, CrrARLns W. Eir- MONS, a citizen of the UnitedStates, residing at Detroit, county of "Wayne, State of Michigan, haveinvented a certain new and useful Improvement in Chair Attachments, anddeclare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which it pertainsto make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to attachments to chairs and has for its objectan improved attachment to childrens high chairs comprising a tray ortable adapted to swing forward and downward.

In the drawings :Figure 1, is a side elevation. Fig. 2, is a sideelevation of the arm to which the tray is secured. Fig. 3, is aperspective of the arm. Fig. 4:, is a perspective of the detached hook.

The chair 1 may be of any standard construction; the tray 2 is ofconvenient shape and is preferably provided with a raised rim 3. Thebrackets 4: upon which the trays rest are preferably of metal, each ispro vided with a standard 5 and a flange 6 with holes 7, through whichare inserted the screws by which the bracket is secured to the tray 2; ahook 8 is pivotally secured to the bracket. The bracket is pivotally andslidingly secured to the seat of the chair 1 by a screw that is driveninto the seat of the chair and passes through a long slot 9 in the endof the arm 4:; a spring 10 secured to the bracket 1 bears against thelever end of the hook and tends to force the bill end of the hookupward. This upward movement of the bill end of the hook is limited by astop engagement which (as shown) is made by bending the sheet metal ofwhich the hook is made across the neck of the hook from a to b. Thecross web at the bent part engages against the edge of the bracket 4; acatch 11 secured to the chair arm is engaged in the notch of the hook;when the hook is made from stamped sheet metal a flange 12 is turned toform a broad bearing for the spring 10, and a flange 13 is turned toform a broad bearing for the finger on the lever arm side of saidhookwhen the hook is swung to disengage it from the catch. The tray swingson the pivot 14: and clears the foot rest 15; because of the slot 9 thetray can swing over the knees of the child. The brackets i are of lengthto hold the tray entirely clear from the chair arms and these are notscratched or marred by it. Lifting the tray does not disengage the hookfrom the catch 11.

The bracket, preferably made from stamped sheet metal is provided withtwo narrow slots 16, 17 that part of the flange 6 which is between theslots 16, 17 is bent to form a shallow loop and the end of the spring 10forced under the loop thus formed.

The tray and its supporting brackets thus.

made can be attached readily to any arm high chair. The tray can bereadily swung from its portion above the chair arm, but because of thecharacter and manner of attaching the spring catch, it is not liable tobe accidentally moved therefrom.

What I claim is 1. An attachment for chairs, having in combination withan arm chair provided with a catch on one arm, a tray, a bracketsupporting said tray and adapted to swing the tray forward, said bracketflaring at its upper end, a hook pivoted to said bracket, the said hookcomprising a sheet metal piece having on one side of the pivot a leverend provided with edges turned in to form flanges for a handle, thecentral portion being bent around said bracket so that the engagement ofthis bent portion with the flaring bracket acts to stop the hook, theother end portion being notched to form a hook engaging with said catchon the chair arm, and a spring adapted to hold the hook in engagement.with the catch, substantially as described.

2. An attachment for chairs, having in combination with an arm chairprovided with a catch projecting from the sideof one of the arms, atray, a bracket supporting said tray and adapted to allow the tray toswing forward thereon, the said bracket comprising a strip of sheetmetal flaring at its upper end and bent into a flange to support thebracket, the said flange being cut and bent to form a loop, a hookpivoted to said bracket and comprising a sheet metal piece at one endhaving inturned flanges at the mid portion bent about said bracket sothat the flare of the bracket forms a stop for the hook, and at theother end notched to engage about the said catch, and a flat springfastened by being inserted in the loop of said bracket and at the otherend engaging the upper flange of-the handle portion of said hook, thesaid spring thereby adapted to yieldingly hold the hook in en gagementwith the catch and be grasped together with the handle portion andcompressed to release the hook from the catch, substantially asdescribed.

3. In combination with a chair having arms and a foot rest, the latterof which is an equal or greater distance below the chair seat than thearms are elevated above, a bracket adapted to be pivoted to the side ,ofthe chair seat and having a slot in which the said pivot engages, thesaid slot being of snfiicient length to allow the bracket to swingbelowsaid foot rest, a tray attached to said bracket, a catch attached to oneof the chair arms, a hook having a notched portion adapted toengage thecatch, pivoted to said bracket and provided. with a lever arm and aspring bearing against said lever arm, and. adapted to hold the hook inengagement with said'catch and remain in engagement during the possiblereciprocat ing movement of said tray, substantially as described 4:. Incombination with a chair provided with arms, and a foot rest, a tray, apair of brackets screwed thereto and attached to pivots in the seat ofsaid chair, the said brackets being provided with slots which engageover said pivots, a catch attached to one of said arms, a pivoted hookattached to said bracket having at one end a notched portion adapted toengage said catch and adapted to maintain engagement with said catchduring the possible reciprocation of said tray, and at the other endhaving each edge flanged, the one flange furnishing a spring, bearingand the other flange furnishing; a finger grip, a fiat spring attachedto the upper portion of said bracket and engaging against the flangedupper portion of said hook thereby pressing said hook into engagementwith said catch, substantially as described.

5. In combination with a chair provided with arms, a catch projectingfrom the side of one arm, a tray, a bracket supporting the tray, thesaid. bracket "being pivoted to swing the tray forward from the arms,and i also adapted to reciprocate lengthwise the Copies of this patentmay be obtained for five cents each, by addressing the Commissioner of.P'atents,

brackets, a hook pivoted to the side of one of said brackets and havinga notched portion engaging the catch from below, the said hook having onthe other side of its pivot a handle portion, and a spring connected tothe tray and adapted to depress the handle portion, thereby thrustingthe notched portion upward in engagement with the catch, whereby thetray is locked against swinging and the hook remains in engagement withthe catch during the limited possible reciprocation, substantially asdescribed i 6. In combination with a chair provided with arms, a tray, abracket supporting said tray and pivoted through a vertical slot thereinto the chair, the said pivoting being arranged to allow the tray to liftabove the chair arms lengthwise of the slot and swing in an aredescribed by such elongated radius, and means for locking the tray tothe chair, whereby the tray in its forward swing may readily clear theknees of the child and the foot rest, substantially as described.

7. In combination with a chair provided with arms, a catch projectingfrom the side of one arm, a tray, a bracket supporting said traya'ndpivoted through a vertical slot therein to the chair seat, the saidpivoting being arranged to allow the tray to reciprocate both the chairarms, assuming a longer radius than when resting above the arms and toswing through: the are of such elongated radius, a hook pivoted to theside of the bracket having a notched portion adapted to engage the catchfrom below and a handle portion forward of the arms, and a springconnected to the tray and engaging against the handle portion, whereby areciprocable tray adapted to clear the childs knees and the foot rest,is securely locked against swinging and the hook remains in engagementwith the catch during the limited possible reciprocation, substantiallyas described.

In testimony whereof, I sign this specification in the presence of twowitnesses CHARLES W. EMMONS. VVitnesses':
